A potted geranium plant sits in a windowsill, absorbing sunlight. After I put this plant in a dark closet for a few days (but keeping it watered as needed), will it weigh more or less (discounting the weight of the water) than before I put it in the closet?
a) It will weigh less because no photosynthesis is occurring, and it is still respiring.
b) It will weigh more because the Calvin cycle reactions continue.
c) It will weigh the same since no biomass is produced.
d) It will weigh more because it still has access to water and soil nutrients.
